Installation

The following gives some overview how to install Reaction components. Please have a look at the documentation if you need more information.

The fastest way to use Reaction is to pull the Reaction Docker images and use them. The following images are needed:

• Reaction database - contains the Reaction database with initial data
• Reaction engine - contains the Tomcat 9 and the Reaction engine web application
• Reaction management app - contains the Reaction management web application on Apache 2

If Docker is not available then the Reaction components have to be installed. There are three main components of Reaction that have to be taken care of.

1. worker The Reaction worker has to be on those machines where log files have to be monitored or operation system commands have to be executed. The installation is easy just execute the following command after the RPM is downloaded:

sudo rpm -i reaction-worker-1.1-1.el7.noarch.rpm

The worker will appear in the /local/reaction/worker-1.1 folder. After the installation only some basic configuration is needed and the worker is ready to run. Please find more information about the installation in the documentation.

2. engine The easiest installation option is to use the standalone mode. All has to be done is to extract the ZIP file, to perform some basic configuration and the engine is ready to run. More information can be found in the documentation.

3. management web application An installation package is provided which helps to install the management web application and all its dependencies More information can be found in the documentation.
